Author presents the measurement of proton anti-proton to Z/gamma* to e+e- + X inclusive differential cross section as a function of boson rapidity. The data, which correspond to an integrated luminosity of 0.4/fb, were collected with DZero detector at Tevatron proton anti-proton collider. At the Run II energy of sqrt{s}= 1.96 TeV, Z bosons are produced with rapidity out to +/-3. The cross section is measured in a mass range between 71 to 111 GeV for the allowed kinematic range.
